next-browser

If next-browser is not already on PATH, install @vercel/next-browser globally with the user's package manager, then playwright install chromium.

If next-browser is already installed, it may be outdated. Run next-browser --version and compare against the latest on npm (npm view @vercel/next-browser version). If the installed version is behind, upgrade it (npm install -g @vercel/next-browser@latest or the equivalent for the user's package manager) before proceeding.

Next.js docs awareness

If the project's Next.js version is v16.2.0-canary.37 or later, bundled docs live at node_modules/next/dist/docs/. Before doing PPR work, Cache Components work, or any non-trivial Next.js task, read the relevant doc there — your training data may be outdated. The bundled docs are the source of truth.
